Hugh Jackman's son showed off his musical skills as he made his stage debut with his father in Toronto, Canada on Tuesday (05Jul11).The X-Men star has a residency at Toronto's Princess of Wales Theatre, entitled Hugh Jackman in Concert, and the show series kicked off on Tuesday. Jackman thrilled audiences with his song-and-dance show and shared anecdotes with the crowd about his life and career. The star sent the concertgoers into a frenzy when his trousers ripped and he had to change onstage, prompting him to quip, "Tom Jones has nothing on me!" But the highlight came partway through the gig as the actor introduced a special guest - his 11-year-old son Oscar. In a post on his Twitter.com page, Jackman writes, "Great 1st show in Toronto... Awesome audience & Oscar made his stage debut playing the didgeridoo. 1 (sic) very proud dad! thx (thanks) 2 (sic) all who came out!"
